I just wanted to say that I feel your pain too - you are not alone in this. I am 35, married with two kids and a church leader. Needless to say that CSA affected my self esteem so much that I despritely felt the need for approval...to feel desired by other men. A few years ago in a very dark time and when I didn't realise these feeling were related to my CSA I did some ammetaur gay porn (solo) and had a profile on a gay site.
I have had guys recognise me (in another town - I didn't know them) and one time I was at the shops with my wife and came face to face with a man I had had sex with a couple of weeks before. How could I be so irresponsible???? I still wait in fear that someone I know will see me on the internet and my dirty secret will be out for all to see.
I understand how this is a real fear for you (and me). The thing I think you have on your side is that you were/are young. Laugh it off as the spontaneity of youth. Like the others said anybody looking at child porn (under 18) has some explaining to do and in reality will be too ashamed themselves to say anything. This is what I think about the gay porn I did - I don't know any gay people so if anyone I know sees it - then they will probably be too ashamed to say anything.
As far as respectability goes I think the truth is the best policy here. If it does come up I think it is ok to 'blame' the CSA for why you acted this way. People will respect you for being honest. Explain that it was a bad part of your life but it is behind you now.
I would probably stay out of politics though. Lol. The past of those guys really get a hammering
It took a lot of courage for you to post this (me too) and I think the positive in this situation is that you can recognise that doing this stuff was not healthy and are taking steps to avoid it in the future.
